Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum foil laminating machines, and particularly relates to a coating machine for preparing aluminum foil composite films. Background Technology

[0002] Due to its excellent properties, aluminum foil is widely used in food, beverages, cigarettes, pharmaceuticals, photographic plates, and household goods, typically as a packaging material; it is also used as a material for electrolytic capacitors; as an insulation material for buildings, vehicles, ships, and houses; and as decorative gold and silver threads, wallpaper, and decorative trademarks for various stationery printed materials and light industrial products. Among these various uses, packaging material is the most effective way to utilize the performance characteristics of aluminum foil. Aluminum foil is a soft metal film that not only has advantages such as moisture resistance, airtightness, light blocking, wear resistance, aroma retention, and non-toxicity and odorlessness, but also has an elegant silvery-white luster, making it easy to process into beautiful patterns and designs of various colors, thus making it more popular.

[0003] Aluminum foil laminating machines are specialized equipment that use solvent-free adhesives to bond aluminum foil with another composite substrate (film, paper, non-woven fabric, textile fabric, etc.).

[0004] The aluminum foil laminating machine includes a material rack, a traction mechanism, a feeding bridge, a roller heating and embossing unit, and a discharge unit. The material rack is equipped with aluminum foil rollers, and the aluminum foil is wound onto the aluminum foil rollers. During the operation of the aluminum foil laminating machine, the aluminum foil rollers rotate under the traction drive of the traction mechanism. During the rotation, the aluminum foil is unwound. The unwound aluminum foil passes through the feeding bridge, is heated and embossed, and then is discharged through the discharge unit.

[0005] In aluminum foil laminating machines, the aluminum foil needs to be coated with adhesive during processing. This process requires the use of an adhesive coating roller and a pressure roller. The gap between the pressure roller and the adhesive coating roller determines the adhesive coating thickness. In actual operation, the adhesive coating thickness standard varies for different aluminum foil composite films, ranging from 0.01 to 0.1 mm. Chinese patent number 2023211747535 discloses a laminating machine for aluminum foil production, including a base with mounting brackets fixedly installed at both ends of the base. The inner... Mounting plates are fixedly installed on both sides, and a mounting mechanism is provided at one end of each mounting plate. A glue removal mechanism is provided between the two mounting mechanisms. The mounting mechanism includes two U-shaped frames, which are fixedly installed at one end of each of the two mounting plates. Slide grooves are provided on the upper and lower sides of the interior of the two U-shaped frames. The lifting and lowering of the pressure roller is achieved by using a cylinder or hydraulic cylinder. However, the lifting height cannot accurately control the gap between the glue coating roller and the pressure roller. Therefore, a new glue coating machine for preparing aluminum foil composite film is needed to meet the needs of preparing aluminum foil composite film with inconsistent glue coating thickness. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coating machine for preparing aluminum foil composite films. This coating machine features U-shaped grooves on both sides of the frame, with bearing seats on both sides of the pressure roller and coating roller positioned within the U-shaped grooves. A lifting mechanism is installed at the top of the U-shaped grooves, which controls the up-and-down movement of the pressure rollers, thereby adjusting the gap between the pressure rollers and coating rollers. This allows for coating different thicknesses of adhesive onto the surface of the aluminum foil strip, facilitating the preparation of different types of aluminum foil composite films and improving production efficiency.

[0007] To achieve the above objectives, this utility model discloses a coating machine for preparing aluminum foil composite film, comprising a base, machine bases disposed on both sides of the base, and a pressure roller and a coating roller disposed between a pair of machine bases. The coating roller is disposed below the pressure roller. The machine base is characterized by having a pressure roller bearing seat and a coating roller bearing seat at both ends of the pressure roller and the coating roller, respectively. A U-shaped groove is provided on the machine base to accommodate the pressure roller bearing seat and the coating roller bearing seat. A mounting plate is provided on the top of the machine base to close the U-shaped groove. A lifting mechanism is provided on the mounting plate, and a lifting rod is provided on the lifting mechanism that passes through the mounting plate, connects to the pressure roller bearing seat, and drives the pressure roller bearing seat to slide within the U-shaped groove.

[0008] Furthermore, a spring is provided between the pressure roller bearing housing and the coating roller bearing housing.

[0009] Furthermore, both the top of the coating roller bearing housing and the bottom of the pressure roller bearing housing are provided with mounting holes for accommodating springs.

[0010] Furthermore, a glue removal plate is provided on the machine base at the aluminum foil strip inlet side, and the glue removal plate is correspondingly located below the glue coating roller.

[0011] Furthermore, a front tension roller is provided on the machine base at the aluminum foil strip inlet, and a rear tension roller is provided on the machine base at the aluminum foil strip outlet.

[0012] Furthermore, the machine base is provided with a height adjustment mechanism for adjusting the height of the front tension roller. The height adjustment mechanism includes a pair of mounting brackets fixed on the side wall of the machine base, a front tension roller mounting seat that slides up and down in the mounting brackets and is installed at the end of the tension roller, and an adjusting screw that is vertically set on the mounting brackets and connected to the front tension roller mounting seat. An adjusting handwheel is provided at the end of the adjusting screw that extends out of the mounting bracket.

[0013] Furthermore, the side wall of the elevator is provided with a gap adjustment wheel for adjusting the height of the lifting rod.

[0014] Furthermore, a guide wheel mounting bracket is provided on the top of the machine base, and a guide wheel is provided at the end of the guide wheel mounting bracket extending obliquely above the front tension roller, with the guide wheel being higher than the top of the pressure roller.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model discloses a coating machine for preparing aluminum foil composite films.
